Introducing Multiple API Keys Support for Liminal Express

With this release, Liminal Express SDK now supports multiple API keys for Vaults’ development environment. Earlier a Vaults organization supported a single API key for executing Express APIs across all user roles. The new feature now enhances security and transparency across wallet and transaction operations by introducing role based access control to manage dev API keys across a Vaults’ organization.

Here are the following supported features:

1. Supports upto 5 active API keys per organization.
2. Supports API key with user roles: Full Access, Admin, Initiator, Signer, and Viewer.
3. Supports the following access permissions:
   1. Wallet operations: Read, i.e., view wallet details and Write, i.e., create new wallet.
   2. Transaction operations: Read, i.e., view transactions and Write, i.e., initiate and sign transactions.
4. Supports full-access level permission for existing organizations until 1st August, 2026. Whereas, newer Vaults’ organizations need to have at least one Signer key with MPC setup completed.
